Abstract (en)

[origin: EP2829398A1] A polylactic acid formed body comprising a polylactic acid base material 1 and a hydrocarbon film 3 vapor-deposited on the surface of the base material by the plasma CVD method, wherein the polylactic acid base material 1 exhibits a sharp X-ray diffraction peak in which a half-width of peak appearing in the 10° - 25° wide angle X-ray measurement is not more than 1.22°, and the hydrocarbon film 3 is vapor-deposited on the surface of the polylactic acid base material 1, and includes two layers of a high CH 2 layer 3a having a ratio of CH 2 per the total of CH, CH 2 and CH 3 of not less than 40% and a low CH 2 layer 3b formed on the high CH 2 layer 3a and having a ratio of CH 2 per the total of CH, CH 2 and CH 3 of not more than 35%. The polylactic acid formed body has the hydrocarbon film vapor-deposited on the polylactic acid base material maintaining very close adhesion through a continuous plasma CVD step without the need of changing over the reaction gas and without causing the polylactic acid base material to be thermally deformed or thermally deteriorated.
